write an equation for the line graphed
Y=_________
pls answer the question cause I really need the answer to this question
Answers
Answer:
y = 3x + 2
Step-by-step explanation:
So we can use the point-slope equation to help us figure out our y = mx +b equation
First we need to choose two points on the graph so we can calculate our slope
I personally like to choose point that intersects two numbers perfectly on the line rather than a point that is maybe half way between two numbers
So we can use the point (0,2) and the point (2,8)
Our (0,2) will represent (x₁, y₁) and our (2,8) will represent (x₂,y₂)
The equation to find the slope is \(m=\frac{y_{2}-y_{1}}{x_{2}-x_{1} }\), so plugging in our values, we get \(m=\frac{8-2}{2-0} =\frac{6}{2} =3\)
We have found our slope, 3, and now we can use the point-slope equation: y - y₁ = m(x - x₁) to figure out the remainder of the equation.
Plugging in our values we get: y - (2) = (3)(x - (0)) which simplifies to y - 2 = 3x which then simplifies to y = 3x + 2

exterior angle is equal to sum of interior opposite angle. so
( 2x + 6 ) + ( 5x ) = ( 8x - 11 )
7x + 6 = 8x - 11
x = 17

Angle BAC is labeled with 72 degree sign, and angle BCD is labeled with 113 degree sign. Write a list of steps that are needed to find the measure of ∠ B . Please help soon!!
Answers
Answer: Sorry I didn't answer sooner!
Step-by-step explanation:
Firstly, you need to know what all angles of a triangle add up to. It doesn't matter what kind of triangle it is, all triangle angles add up to 180 degrees. The first thing you would want to do is add 72 to 113. Then subtract your answer from 180, 180 - __ =? By doing this you will find the measure of angle B. Hope this helps!

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

so 2 times

Answer:
There are 2 bricks in the bag.
Step-by-step explanation:
Let n represent the number of bricks in the bag. Then:
(3/4 lb)n = 1 1/2 lb total; find n by dividing both sides by (3/4 lb)/brick:
1 1/2 lb
n = --------------------- = 2 bricks
3/4 lb/brick
There are 2 bricks in the bag.

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

To solve for e in the inequality -16+e>9, we can start by isolating e on one side of the inequality.
We can begin by adding 16 to both sides of the inequality to cancel out the -16:
-16 + e > 9
-16 + e + 16 > 9 + 16

A random sample of the 900 passengers boarding a plane was asked if they had ever flown before.
Have flown before: 32 Have not flown before:18
Write a proportion that can be used to determine how many passengers have probably not flown before.
Answers
324 passengers
Step-by-step explanation:Total number of passengers that were boarding the plane = 900
Part of ratio of people who have flown a flight before = 32
Part of ratio of people who have not flown a flight before = 18
Ratio of the people who has flown to who has not flown a flight = 32 : 18
Sum of both the parts of ratio = 32 + 18
= 50
Total number of people who has flown a flight before = 32/50 * 900
= 576 people
Total number of people who has not flown a flight before = 18/50 * 900
= 324 people
Proportion = 32 : 18 :: 576 : 324
Hence, the number of people who has not flown a flight before is 324.

A factory can work its employees no more than 5 days a week, and no less than 2 days per
week. Create an inequality to represent the range of days an employee can work. Solve the
inequality to determine the range in hours. Show all of your work and explain each of your
steps. Explain your answer.
Answers
Answer:
2 ≤ x ≤ 5
Step-by-step explanation:
If x = number of days worked
According to the question:
Employees cannot work for more than 5 days per week: that is maximum working days per week is 5 - - - (1)
x ≤ 5 - - - (1)
Employees cannot work for less Than 2 days per week, that is minimum working days per week is 2 days
x ≥ 2 - - - (2)
Combining both conditions (1) and (2) such that the both Inequality sign are the same :
If x ≥ 2 ; then 2 ≤ x
Combining 2 ≤ x and x ≤ 5
We have ;
2 days ≤ x ≤ 5 days
